Uuh, in that case, don't be disappointed, because it is only similar in concept, and not actually a double.
For example the world is not split into humans and other races, but there are societies hiding right between them.
The mechas are also alot more present, better say "dominating", and the whole world is in a quite undefinable technological state, that is industrialized no doubt, but yet the world is underpopulated and even kind of primitive in alot of areas (usual FF-futuristic setting?
). So it is definitly not 'fantasy - but with lost logia', like Anima.
The religious thematic is also quite obscure and doesn't have anything to do with the gnosis/natura apparatus we see in Anima. The only thing I see is this soul-mill/engine/worldprinciple topic, but that is present in alot of other settings too, not to mention that it is roughly taken an ancient idea preceding even the greeks. Quite the coincidence to have it around in both settings though.
So you won't really get a clone of Anima's setting, but you will naturally find alot of similarities.
The main reason is this power in the shadows thing I guess, because it is quite unique. Without it, I would just judge it as as much similiar as alot Animes and JRPG's must be similiar to Anima, because they are just part of the same genre.
